With the development of terminal technology, mobile terminals have begun to change from simply providing telephony devices to a platform for running general-purpose software.

The dual mode terminal can operate in two modes, such as a global system for mobile communications (GSM) mode and a Code Division Multiple Access (CDMA) mode, and can rapidly switch the modes according to a network condition or a user selection, thereby satisfying a demand of diversified communication consumption of the user. The existing dual-mode terminal has two implementation modes, one is a dual-mode switching operation mode, and the other is a dual-mode independent operation mode. In the dual-mode switching mode of operation, only one mode is in operation at a time. In the dual-mode independent operation mode, the dual modes can be in standby mode at the same time, namely the dual modes operate at the same time and receive broadcast and paging messages of respective network sides. The dual-mode independent operation mode does not need the cooperation of a network side, and the realization mode is simple.
However, for the dual-mode independent operation mode, under the condition that the dual-mode frequency band is close, the interference between two services of the terminal is relatively increased, so that the service quality is reduced, even the terminal is unusable, and the user experience is influenced. The prior art mainly reduces the influence caused by interference by reasonably arranging the position of an antenna and adding a plurality of filter devices. This effect cannot be reduced further due to constraints such as the spatial location of the termination, the performance of the filter device, etc. Therefore, it is necessary to further reduce the mutual interference between the frequency bands by other means to reduce the influence of the interference.

Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present invention are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the invention and should not be taken as limiting the invention with regard to other embodiments that are not detailed herein.
In the description that follows, specific embodiments of the present invention are described with reference to steps and symbols executed by one or more computers, unless otherwise indicated. Accordingly, these steps and operations will be referred to, several times, as being performed by a computer, the computer performing operations involving a processing unit of the computer in electronic signals representing data in a structured form. This operation transforms the data or maintains it at locations in the computer's memory system, which may be reconfigured or otherwise altered in a manner well known to those skilled in the art. The data maintains a data structure that is a physical location of the memory that has particular characteristics defined by the data format. However, while the principles of the invention have been described in language specific to above, it is not intended to be limited to the specific form set forth herein, but on the contrary, it is to be understood that various steps and operations described hereinafter may be implemented in hardware.
The principles of the present invention are operational with numerous other general purpose or special purpose computing, communication environments or configurations. Examples of well known computing systems, environments, and configurations that may be suitable for use with the invention include, but are not limited to, hand-held telephones, personal computers, servers, multiprocessor systems, microcomputer-based systems, mainframe-based computers, and distributed computing environments that include any of the above systems or devices.
The details will be described below separately.
The embodiment will be described in terms of a radio frequency interference processing apparatus, which may be specifically integrated in a terminal, where the terminal may be an electronic device with a communication function, such as a mobile interconnection network device (e.g., a smart phone, a tablet computer).
Referring to fig. 1, fig. 1 is a schematic flow chart of a radio frequency interference processing method according to an embodiment of the present invention, where the radio frequency interference processing method according to the embodiment includes:
step S101, respectively obtaining an initial first frequency band and an initial second frequency band used by a first communication module and a second communication module in a terminal.
In the embodiment of the invention, the terminal can be a dual-card dual-mode terminal and comprises two communication modules, the two communication modules can establish two communication services simultaneously, and each module corresponds to an SIM (USIM) card.
Each mode supported by a multimode terminal may generally support multiple frequency bands, for example: the GSM (global system for mobile communications) system can support GSM900 (uplink 890-915MHz, downlink 935-960MHz) and DCS1800 (uplink 1710-1785MHz, downlink 1805-1880MHz) frequency bands; the TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, TD for short) system can support the A frequency band (2010-2025MHz) and the F frequency band (1880-1900 MHz); the LTE (Long term evolution) system can support 39 band (1880-1920MHz), 40 band (2300-2400MHz), and so on.
When a dual-mode terminal performs multiple services simultaneously (e.g., using a GSM network for voice services, using a TD-SCDMA or LTE network for data services, etc.), if frequency bands allocated by two networks have overlapping portions, interference between the two services of the terminal is relatively increased, resulting in reduced service quality, or even being unusable.
In an embodiment, there may be multiple methods for acquiring a network frequency band currently used by a communication module in a terminal, for example, acquiring information of a communication system currently used by the communication module, and then determining that frequency band information corresponding to the communication system currently used by the terminal is stored in a user information database according to identification information of the terminal and the communication system currently used by the terminal, where the frequency band information at least includes the current communication frequency band of the terminal. The user information database at least comprises identification information of the terminal, a communication system currently used by the terminal and the corresponding relation between the frequency band information.
The communication system may be a 2G (2nd generation, second generation mobile communication technology) communication system such as GSM, a 3G (3rd generation, third generation mobile communication technology) communication system such as WCDMA (Wideband Code Division Multiple Access), a 4G (4th generation, fourth generation mobile communication technology) communication system such as LTE, and the following communication systems. The communication system currently used by the terminal is acquired, and the activation state of each system of the terminal can be inquired in a management system corresponding to each of 2G, 3G or higher communication technologies of the access network through the identification information of the terminal, so that the currently used network system is determined.
In an embodiment, the Identification information of the terminal may be information with an Identification function, such as an IMSI (International mobile subscriber identity Number), which is not listed herein in the embodiments of the present invention.
Step S102, determining whether there is an overlapping frequency band between the initial first frequency band and the initial second frequency band, if yes, executing step S103, and if no, ending the process.
In an embodiment, it may be determined whether there is a strength value of a radio frequency signal that satisfies both the initial first frequency band and the initial second frequency band, and if so, it is determined that there is an overlapping frequency band between the initial first frequency band and the initial second frequency band. And if not, determining that the initial first frequency band and the initial second frequency band do not have the overlapped frequency band.
For example, the currently used network standard of the first communication module is a, the corresponding frequency band is 1800-1900MHz, the currently used network standard of the second communication module is B, and the corresponding frequency band is 1890-1990HMz, and thus it can be known that the radio frequency signal with the strength within the 1890-1900MHz frequency band can satisfy both the interval of the initial first frequency band and the interval of the initial second frequency band, that is, it is determined that a part of the overlapping frequency band exists between the initial first frequency band and the initial second frequency band.
Step S103, when the first communication module in the terminal enters a communication state, the initial second frequency band is adjusted, so that the initial first frequency band and the adjusted initial second frequency band are staggered.
In the embodiment of the present invention, the terminal receives a signal sent by a base station to complete a communication function, where the base station may be a base station of a wireless local Area network (lan) based on wireless fidelity (wifi) (wireless fidelity) standard, may be a base station of a global System for Mobile communication (gsm), or may be a base station of bluetooth. The terminal transmits and receives various types of data based on wireless communication controlled by the base station. For example, a terminal may receive content data from a content distribution server via a base station, and may transmit and receive e-mails to and from another terminal. The content data may include, among others, music data such as music, radio, and the like, visual data such as moving pictures, television programs, videos, photographs, and the like, and any other data such as games, software, and the like.
The main function of the base station is to provide wireless coverage, i.e. to enable wireless signal transmission between a wired communication network and a wireless terminal. Therefore, the position of the base station in the communication network is shown in fig. 2, the control signaling, voice call or data service information on the core network side is sent to the base station through the transmission network (in 2G, 3G, 4G networks, the signal is first sent to the base station controller and then to the base station), the signal is processed by the baseband and the radio frequency on the base station side, and then sent to the antenna through the radio frequency feeder line for transmission, the terminal receives the radio wave transmitted by the antenna through the radio channel, and then demodulates the signal belonging to itself.
In an embodiment of the present invention, after the terminal receives the radio frequency signal, the terminal needs to be distributed by the power distributor, wherein the power distributor is a device capable of dividing one path of input signal energy into two or more paths of output equal or unequal energy, and a final radio frequency signal is obtained after distribution.
When the first communication module receives the radio frequency signal from the base station and enters a communication state, the second frequency band is adjusted so that the first frequency band and the second frequency band are staggered.
For example, the second frequency band is adjusted to 1900-. The interference between the two frequency bands is effectively reduced.
Of course, it should be understood that, after determining that there is an overlapping frequency band between the first frequency band and the second frequency band, the method may further include:
when a second communication module in the terminal enters a communication state, the first frequency band is adjusted so that the first frequency band and the second frequency band are staggered.
As shown in fig. 3, fig. 3 is an application schematic diagram of the radio frequency interference processing method according to the embodiment of the present invention. In the embodiment of the present invention, the first network system may be a GSM network system, the second network system may be an LTE network system, and a frequency band currently used by the GSM network system and a frequency band currently used by the LTE network system have an overlapping frequency band. When a terminal establishes a data service through an LTE network, the terminal initiates a voice service connection under the LTE network, and at the moment, the frequency band of the GSM network is adjusted so that no overlapping frequency band exists with the frequency band used by the LTE network. When the terminal initiates the voice service connection interruption in the LTE network, the frequency band of the GSM network is readjusted to be restored to the original frequency band.
As can be seen from the above, the radio frequency interference processing method provided in the embodiment of the present invention can respectively obtain the first frequency band and the second frequency band used by the first communication module and the second communication module in the terminal, and determine whether the first frequency band and the second frequency band have overlapping frequency bands, if so, when the first communication module in the terminal enters a communication state, the second frequency band is adjusted, so that the first frequency band and the second frequency band are staggered. The invention can adjust the frequency bands of the two communication modules of the dual-mode terminal, so that when one communication module carries out communication, the radio frequency interference caused by the other communication module is reduced, thereby improving the signal quality and the user experience.
The radio frequency interference processing method of the present invention will be further explained below according to the description of the previous embodiment.
Referring to fig. 4, fig. 4 is a schematic flow chart of another radio frequency interference processing method according to an embodiment of the present invention, including:
step S201, respectively obtaining an initial first frequency band and an initial second frequency band used by a first communication module and a second communication module in a terminal.
The first communication module uses a first communication system, and the second communication module uses a second communication system. The method for acquiring the communication system currently used by the terminal and the frequency band information corresponding to the current communication system used by the terminal from the terminal may include:
sending request information to a terminal, wherein the request information is used for requesting the terminal to send communication system and frequency band information of the terminal;
and receiving response information sent by the terminal, wherein the response information comprises the communication system and the frequency band information of the terminal.
Optionally, the request information may be sent to the terminal by a management system of the access network when the terminal is in a service state.
It should be noted that the frequency band information obtained in the above steps may include the current communication frequency band of the terminal and the frequency band support capability of the terminal, that is, the current communication frequency band of the terminal and the frequency band support capability of the terminal are obtained together, or may be obtained separately, which is not further limited in the present invention.
In an embodiment, there may be multiple methods for acquiring a network frequency band currently used by a communication module in a terminal, for example, acquiring information of a communication system currently used by the communication module, and then determining that frequency band information corresponding to the communication system currently used by the terminal is stored in a user information database according to identification information of the terminal and the communication system currently used by the terminal, where the frequency band information at least includes the current communication frequency band of the terminal. The user information database at least comprises identification information of the terminal, a communication system currently used by the terminal and the corresponding relation between the frequency band information.
Step S202, determining whether there is an overlapping frequency band between the initial first frequency band and the initial second frequency band, if yes, performing step S203, and if no, performing step S204.
Step S203, calculating an overlapped frequency band in the initial first frequency band and the initial second frequency band.
For example, the currently used network standard of the first communication module is a, the corresponding frequency band is 1800-1900MHz, the currently used network standard of the second communication module is B, and the corresponding frequency band is 1890-1990HMz, and thus it can be known that the radio frequency signal with the strength within the 1890-1900MHz frequency band can satisfy both the interval of the initial first frequency band and the interval of the initial second frequency band, that is, it is determined that a part of the overlapping frequency band exists between the initial first frequency band and the initial second frequency band. The overlapping frequency band is 1890-1900 MHz.
Step S204, determining the frequency band outside the overlapped frequency band in the initial second frequency band as the target frequency band.
Step S205, adjusting the initial second frequency band to the target frequency band.
For example, in the 1890-. The interference between the two frequency bands can be effectively reduced.
Step S206, when the first communication module in the terminal exits the communication state, the adjusted initial second frequency band is reset to the initial second frequency band.
In an embodiment, after the first communication module finishes the call, i.e. exits the communication state, the adjusted second frequency band may be reset to the initial second frequency band, for example, to the 1900-.
In the embodiment of the present invention, the initial second frequency band of the second communication module is adjusted after the first communication module enters the communication state, and in other embodiments, the initial second frequency band of the first communication module may be adjusted after the second communication module enters the communication state.
As can be seen from the above, in the embodiments of the present invention, the initial first frequency band and the initial second frequency band used by the first communication module and the second communication module in the terminal may be respectively obtained, whether there is an overlapping frequency band in the initial first frequency band and the initial second frequency band is judged, if yes, an overlapping frequency band in the initial first frequency band and the initial second frequency band is calculated, a frequency band other than the overlapping frequency band in the initial second frequency band is determined as a target frequency band, the initial second frequency band is adjusted to the target frequency band, and when the first communication module in the terminal exits from the communication state, the adjusted initial second frequency band is reset to the initial second frequency band. The invention can adjust the frequency bands of the two communication modules of the dual-mode terminal, so that when one communication module carries out communication, the radio frequency interference caused by the other communication module is reduced, thereby improving the signal quality and the user experience.
